The Seattle Sounders on Monday finally confirmed the season-long loan of forward Fredy Montero to Colombian club Millonarios, but also announced that he had signed a new multiyear deal with the MLS club.

Montero, 25, is Seattle’s all-time leading scorer and has tallied 60 goals and 43 assists in all competitions over the past four years. His 47 goals in MLS regular season play are the third-most in the league over the same span.

But Montero’s inability to finish in the playoffs—he has no goals in 10 career postseason games—and his second-half removal from Seattle’s Western Conference finals decider vs. the L.A. Galaxy led many to assume a change in scenery was needed.

"Fredy has been a fantastic player and pro,” Sounders GM Adrian Hanauer said. "We wish Fredy the best of success with Millonarios as he continues to develop as a player. We hope this move helps Fredy's chances of being called up to the Colombian national team, as he has certainly earned it."

Montero last played for his country in 2009.

By re-signing Montero and holding on to his rights, Seattle will be in position to either welcome him back for the ’14 campaign or profit through a deal with Millonarios.

The Bogotá club won its 14th Colombian league title last month—its first in 24 years—and will play in the Copa Libertadores this spring. Its first-round group includes Club World Cup champion Corinthians and Mexican titlist Club Tijuana, home to American players Joe Corona, Edgar Castillo and Greg Garza.

Montero made $756,000 last season and was a designated player. Terms of his new deal weren’t disclosed. Seattle’s attack now will be led by U.S. national team forward Eddie Johnson, who had 24 goals in 2012, and former reserves David Estrada and Sammy Ochoa.
